RIVETING nnvrcn.

Application filed January 9, 1922. Serial No. 527,992.

to provide means for expanding the end of" a rivet in securing one member to a second member the rear side of which is not readily accessible, as for example in securing a name plate tothe body of an automobile or like vehicle, the body of which is constructed of sheet metal. Obviously, the invention is adapted for securing any device to sheet metal or any two members together where the rear end is not readily accessible; The present invention is an improvement over our invention disclosed in Letters Patent Number 1,340,77 8 issued May 18, 1920.

A further object of the invention is to provide a device f this nature which will be of extremely simple, durable and inexpensive construction, one which is efficient and reliable in operation, and well adapted to the purpose for whichit is designed.

With these and numerous other objects in view, the invention resides in certain novel features of construction, and the combination and arrangement of parts as will be 3 hereinafter fully described and claimed.

In the drawing Figure 1 is an elevation of the tool show- .ing the same in operation,

Figure 2 is a longitudinal section there through,

Figure 3 is a transverse section there through taken on the line 3 3 of Figure 1 looking in the direction of the arrow,

Figure 4 is a perspective view ofthe rivet, and

Figure 5 is a plan view showing the rivet holding a plate to a piece of sheet metal.

,Referring to the drawing in detail it will be seen that a sleeve 1 is provided with the longitudinally extending diametrically opposed slots 2 and. is internally threaded for the purpose of receiving the bit 3 which is threaded at one end and has the diametrically opposed lugs 4 situated intermediate its v ends which are formed preferably by a pin 5 passing transversely through the bit. These lugs 4 extend into the slots 2 so as to key the bit 3 to the sleeve 1. The sleeve 1 is provided at one end with the diametrically opposed parallelly extending legs 7 for supporting the conical shaped block 8 at their ends. This block 8 is provided with a central bore as is also the adjacent end of the bit 3. A thumb nut 9 is adapted to be threaded on the threaded end of the bit 3 whereby the bit may be drawn through the sleeve toward the nut when so desired and for a purpose to be later set forth. A set screw 10 is situated in the drill 3 so as to communicate with the bore thereof for the purpose of holding a wedge pin 11 in the bit as is disclosed to advantage in Figures 1 and 2.

This wedge bit 11 is provided with a head 12 at its outer end.

The rivets used in connection with this tool, as shown in Figure 4, are provided with or formed with a disk 13 having a central opening and the right angularly extending semi-cylindrical portions 14 which are normally disposed so as to form a cylinder. In considering the structure in Figure 1 wherein it is desired to attach the plate 15 to the sheet metal 16, it will be seen that the wedge pin is first inserted into the rivets so that its head 12 will be situated adjacent the ends of the semi-cylindrical portions 14 after which the rivet and pin is passed through the apertures in the plate 15 and sheet metal 16. The other end of the pin 11 is then passed through the bore of the block 8 into the bore of the bit 3 and fixed thereto by the set screw 10. The nut 9 is now rotated so as to draw the bit 3 into or away from the block 8 -thereby causing the wedge head 12' to separate the semi-cylindrical portion 14 wherebyfthey will take a position somewhat similar to that disclosed to the left of Figure 1. When the pin 11 has been pulled as fan as is possible the same is disconnected fr'om the bit 3 and may be pushed through the opening in the rivet. Sometimes, f course, it will be necessary to cut the pin adjacent the disk portion of the rivet and in such cases another pin or. suitable instrument may be used for pushing the pin through the rivet out of sight.

Having thus described our invention what we claim as new is A fastener setting apparatus comprising bit for engaging the shank portion of said in combination, a pin having a shank porpin, and means on said frame for moving tion adapted to pass through a hollow fassaidbit, tener which is to be set and a head portion In testimony whereof we affix our signa- 5 larger than said hollow fastener adapted to tures in presence of two witnesses.
